For the ceramic materials, the effects of additives such as pbo, b2o3, co2o3, mno2, cr2o3, sb2o3 on the electrical properties of bismuth - free zno - glass varistor were studied. the glass phase formed mainly by pbo and b2o3 during sintering process could decrease the sintering temperature, improve grain uniform growth and inhibit grain second growth. nonlinear property could be improved by properly adding co2o3, mno2, and cr2o3
對瓷料而言，系統研究了非bi系zno -玻璃料配方體系中pbo 、 b2o3 、 co2o3 、 mno2 、 cr2o3 、 sb2o3等添加劑對壓敏電阻電性能的影響規律，其中， pbo 、 b2o3在燒結過程中形成的玻璃相，可降低燒結溫度，促進晶粒均勻生長，抑制晶粒二次長大， co2o3 、 mno2 、 cr2o3做為非線性添加劑，適量添加可提高樣品的非線性， sb2o3做為改性添加劑，在燒結過程形成的尖晶石相可細化晶粒，抑制晶粒二次生長，改善樣品的綜合電性能。 -
It shows with the increase of the amount of the mo in the si - mo infiltrant, the density of the infiltrated materials with the same performs increased, but the amount of the free carbon and pore also increased. it was the result of the capillary chocking - off caused by the separation of the mosj2 from the alloy infiltrant during the sintering process. after th thermal treatment at 2050, the amount of the free carbon and pore decreased. also. another cause for the unfully conversion of c into sic was the gas pressure. larger than the capillary force
實驗表明，對于同一坯體，隨著si - mo熔體中mo含量的增加，浸滲所得材料的密度隨之增加，但是，材料中的殘留c 、氣孔相的含量亦隨之增加。這是由於反應浸滲時，熔體中析出的mosi _ 2阻塞毛細管造成的。含殘留c 、氣孔相的材料進行高溫（ 2050 ）熱處理后，材料中殘留c 、氣孔相的含量大大減少。 -
